WILLIAM T. BLAND, OF CI-IATTANOOGA, TENNESSEE.

HEATING APPARATUS.

To all whom it may concern Be it known that I, WILLIAM T. BLAND, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in heating apparatus and has relation more particularly to a device of this general character capable of being employed for a plurality of different purposes and an object of the invention is to provide a novel and improved device of this general charactor of a portable type and wherein the parts comprised therein may be assembled in a convenient and expeditious manner for a purpose for which it may be intended to be used.

It is also an object of the invention to provide a device of this general character of a novel and improved character which. may be used in connection with food stuffs and whereby the various products of the farm, orchard and garden may be preserved in such a way as to retain the natural food flavors together with their nutrientelemcnts and thus prevent the loss of their food values.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the ac companying drawings, wherein Figure 1 is a view in end elevation, partly in section, of a heating apparatus constructed in accordance with an embodiment of my invention, and assembled for the purpose of preserving; F ig. 2 is a vertical longitudinal sectional view taken substantially centrally of Fig. 1; Fig. 8 is a fragmentary longitudinal sectional view illustrating the device as assembled for the purpose of canning; Fig. 1 is a view, detached, in perspective of the supporting rack as set forth in Specification of Letters Patent.

Fig. 3; Fig. 5 is a view in elevation and partly in section of a drying or evaporating attachment adapted to be employed in con nection with my invention as herein disclosed; Fig. 6 is a fragmentary view in top plane of the controlling vent shown in Fig. 5. Fig. 7 is a view somewhat similar to Fig. 2 but illustrating a still further embodiment of my invention.

As disclosed in the accompanying drawings, 1 denotes a fire box or furnace of portable type preferably constructed from suitable castings and sheet metal and including spaced walls 22 affording thcrebctwcen a dead air space S lined with asbestos, as indicated at 4, whereby an effective insulating means is provided to retain the heat generated within the fire box or furnace. As it is immaterial as to the character of the furnace, a further detail is believed to be unnecessary as if the conditions require it may burn either oil, gas or any fuel. When applied in position for use, I iind it best that such fire box or furnace be rested upon the base 5 which is preferably provided with a. seamless bottom 6 and having produced in its sides below such bottom 6 the openings or perforations 7 to afford a circulation therethrough of cold currents of air whereby the surface on which the furnace is supported, especially should such surface be a wood flooring, is effectually protected against the heat of the lire box or furnace.

in suitable communication with the furnace is the flue or stack 8 which is adapted to be supported by a pedestal or base member 9, as is particularly illustrated in the accompanying drawings.

One face of the fire box or furnace 1 is provided with a conventional fire door 10 while produced in such face or wall beneath such fire door is a draft opening 11, heroin disclosed as under control of the sliding door 12, such draft opening 11. also affording a means whereby tools such as soldering irons may be conveniently inserted when it is desired to heat the same.

The upper or top portion of the fire box or furnace 1 is substantially open and is provided with the outwardly directed flanges 14 adapted to serve as a. point of suspension for a receptacle adapted to entirely close such open portion or top of the fire box or furnace 1 when applied in operative position relative to such furnace or fire box, such receptacle being provided at a predetermined point upon its sides with the outwardly directed flanges adapted to rest upon such flanges let and to limit the insertion or entry of the receptacle within the furnace or fire box. As is particularly shown in Figs, 1 and 2 of the drawings, the receptacle 16 is in the nature of a boiler or cooker, the walls thereof below the flanges 15, as indicated at 17, being inclined inwardly so that the fire within the furnace or box 1 may completely surround the same to its point of suspension, whereby a greater heating surface will be aflorded and which will therefore result in quicker action upon the water contained within such boiler or cooker 16. The base of the boiler or cooker 16 is provided at substantially its transverse center and entirely thereacross with the depression or channel 18 substantially semi-circular in cross section, as herein disclosed, and in which is adapted to partially extend an inclosed cylinder or drum 19 provided in its heads or ends with trunnions 20 or the like adapted to be accommodated within suitable sockets 21 suitably affixed to the end walls of the container 16 whereby the cylinder is capable of axial movement and whereby it may be removed or applied with convenience. The cylinder 19 is of such a diameter as to afford therebetween and the adjacent wall of the depression 18 a shallow passage for the fluid within the container so that the resultant expansive force of the fluid therein due to the action of the heat from the furnace or fire box 1 will so coact with the longitudinally directed cleats 22 projecting from the cylinder 19 as to cause the same to rotate rapidly and which rotation will result in a thorough circulation of the fluid within the container 16 and thus assuring a constant and uniform degree of heat throughout. To further assure a substantially immediate heating of the fluid within the re ceptacle 16, I have depending from the bottom thereof and to either side of the depression or channel 18 and positioned in a vertical plane substantially parallel with the vertical plane of the depression or channel 18 the pipes 23 having their opposite ends, as at 24, in suitable communication with the interior of the receptacle 16. These pipes are adapted to be positioned directly in the fire within the furnace or box 1 and, as is believed to be clearly apparent, will also serve in the nature of a superheater.

lVhen it is desired to employ the furnace and the container 16 for the purposes of preserving, I employ, as particularly shown in Figs. 1 and 2, the receptacle 25 which is adapted to project within the container 16 and to close the upper or top portion thereof, the upper marginal portions of the walls of such container 16 being provided with the outwardly directed flan es 26 adapted to afford a point of suspension for the receptacle 25, such receptacle having its side walls provided with the outwardly directed flanges 27 which are adapted to contact with and resting upon the flanges 26, the walls of the receptacle 25 below the flanges 26 are inclined inwardly so that the heated fluid within the container 16 or the steam generated therefrom may completely surround such lower portion in order to assure and maintain a higher degree of temperature within the receptacle. To further assure the proper action upon the products placed within the receptacle 25 for preserving, I provide, as herein disclosed, such receptacle 25 at substantially its transverse center with a plurality of vertically alined tubes or pipes 28 through which the heated fluid or the steam generated therefrom may circulate. As is believed to be obvious the top or open face of the receptacle 25 is adapted to be hermetically closed by the top or cover 29 capable of removable engagement therewith.

lVhen it is desired to employ the furnace and the container 16 for the purposes of can ning the receptacle 25 is removed and rested upon the bottom of such container 16 is the rack member or false bottom 30 herein disclosed as comprising spaced elongated bars 31 having their extremities bent downwardly on a curve, as at 32, to afford supporting feet for such bars while the intermediate portions thereof are tied or connected by the spaced cross bars 33. By this arrangement it will be seen that a supporting rack or false bottom is afforded which will not interfere with the action or circulation of the fluid or steam generated therefrom within the container 16. Upon this rack member or false bottom 30 is adapted to be positioned, as particularly shown in Fig. 3, the container 34 having its walls perforated, as at 35, and in which container is adapted to be placed in a conventional manner the receptacles 36 containing the products tobe canned or bottled. It is thought to be obvious that by this arrangement the container 31 will be completely submerged within the fluid contained within the container 16 and that the perforations 85 will assure the proper action of the heated fluid or steam upon the receptacles 36 and in order to facilitate the application or removal of the container 34 within the container 16, I provide such container 34 with the bails or handles 37.

Should it be desired to employ the furnace or fire box for the purpose of a drier or an evaporator the receptacle 3S, particularly shown in Fig. 5, is adapted tobe employed, such receptacle being provided adjacent its base or bottom with the flanges 39 adapted to rest upon the flanges 14 of the furnace or fire box 1, the portion 40 of the receptacle 38 below the flange 89 being in the nature of a hot air drum for radiating heat through the chamber afforded by the receptacle 38, such drum, as is believed to be clearly apparent, being projected or extended within the chamber of the furnace or fire box. As herein disclosed, the receptacle 38 is provided therein with a plurality of supporting shelves 4-1 and has one face thereof open and adapted to be closed by the hingedly mounted doors 42 while in the upper marginal portions of such receptacle are the openings as affording a ventilating means, while the top of such receptacle is provided with the controllable vent 44 for regulating the heat within such receptacle 38.

I have also found in practice that the container 16 may be employed with facility as a laundrying device and in which instance the rack member or false bottom 30 and, if the requirements of practice may so dictate, the cylinder 19 are removed and the cover 29, hereinbefore referred to, be employed to close the upper or open end thereof after the clothing to be cleansed have been applied within the receptacle 16, the action of the superheated steam generated within the pipes 23 upon the clothes being such as to obviate the necessity of any special attachment for agitating such clothes.

If preferred, the furnace or fire box may be of such a size as to permit a second boiler being employed alongside of the container 16 when the device is being used for launclrying purposes and in which instance the clothing as removed from such receptacle 16 may be inserted for the purpose of rinsing the same, such arrangement being illustrated in Fig. 7 of the accompanying draw- 111 's.

I rom the foregoing description it is thought to be obvious that a heating apparatus constructed in accordance with my invention is of an extremely simple and com paratively inexpensive nature and is particularly well adapted for use by reason of the plurality of differing purposes for which it may be employed and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

Having thus fully described my invention what I desire to secure and claim by Letters Patent is:

1. In combination with a fire box having its upper face open, of a container adapted to be supported by the fire box and close the opening therein, the base of such container being provided with a depression, and a cylinder mounted for rotary movement projecting within such depression.

2. In combination with a fire box having its upper face open, of a container adapted to be supported by the fire box and close the opening therein, the base of said container being provided with a depression, and a cylinder removably mounted for rotary movement Within the container and projecting within such depression.

3. In combination with a fire box having its upper face open, of a container adapted to be supported by the fire box and close the opening therein, the base of such container being provided with a depression, and a cylinder mounted for rotary movement within such container and projecting within the depression, the lower portion of such. cylinder being in close proximity to the wall of the depression.

4. In combination with a fire box having its upper face open, of a container adapted to be supported by the fire box and close the opening therein, the base of such container being provided with a depression, a cylinder adapted to be rotatably supported within the depression, and superheating means depending from the container at opposite sides of the depression and disposed in substantial parallelism with the depression.

5. In combination with a fire box having its upper face open, of a container adapted to be supported by the fire box and close the opening thereof, the base of said container being provided with a depression, a cylinder adapted to be rotatably supported within the depression, and superheating means depending from the container.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
